READING-GLASS HOLDER.

1 Application filed .Tune 19,

To all whom it may concern.-

' Be it known that 1, JOHN T. SPRADLING, a

citizen of the United States, and a resident of lVhite Plains, in the county of Vestchester and State of New York, have invented a new and Improved Reading-Glass Holder, of which the following-is a full, clear, and exact description.

This invention relates to new and useful improvements in holders for magnifying glasses, and pertains more particularly to means for supporting a reading glass.

The primary object of the invention is to provide a reading glass'holder for use in connection with type-setting machines for the purpose of more clearly bringing out the manuscript of the copy from which the operator is working.

A further object of the invention is to construct a device of this character in such a manner that the reading glass is movable with respect to the manuscript copy.

A still further object of the invention is to construct a device of this character so that the reading glass is automatically returned to its starting point.

With the above and other objects in view,

reference is had to the accompanying drawin s, in whichigure 1 is a segmental elevation of a portion of a type-setting machine showing the location of the device with res ect to the copy holder and'keyboard thereof Fig. 2 is a sectional view on the line 22 of Fig. 1;

Fig. 3 is a detail top plan view.

Referring more particularly to the drawings, the reference character 5 designates the keyboard of a machine and supported from said keyboard in any desired manner, as by means of brackets 6, is the copy board 7.

Extending upwardly from the rear edge of the copy board 7, are two brackets 8, said brackets being secured in place by means of rivets or the like 9. The upper end of each of said brackets 8 is bent outwardly as at 10, and said brackets are each secured as at 11, to a transversely-extending rod or track '12. One end of this track 12 is bent downwardly as at 13, and mounted in the free end of the downwardly-extending portion 13, v is a spring drum 14, said drum being freely rotatable on the screw 15, which secures it to the end of the track.

The reference character 16 designates a Specification of Letters latent.

reading glass, which is supported over the keyboard 7 by means of a bracket 17, said bracket being bolts or the like 19, to a traveling carriage 18, which latter is adapted for movement along the track 12. The carriage 18 haseach of its free ends bent backwardly upon the body portion 21, as designated by the reference character 20, the said free ends being arranged in spaced relation to each other to permit of movement of the carriage along the track 12. Mounted between each of the free ends 20 and the body portion 21 of said carriage 18, are rollers 22, and, as shown in Fig. 2, said rollers are adapted to engage the opposite side faces of the track 12. As shown in Fig. 2, these rollers are angularly disposed with relation to each other which angular disposition causes a binding action on the track 12, thus preventing the carriage from rocking under the weight of the reading glass 16, to a position where it would be in operative relation to said track.

Extending around the spring drum 14, is a suitable flexible cord 24, the free end of said flexible cord being attached, as at 25, to said carriage 18, for a purpose to be hereinafter described. 7

Depending from the track 12 on the opposite end to that on which the spring drum 14 is mounted, is an arm 26, and mounted in the opposite" end of said arm 26, are

rollers 27 and 28. r

The reference character 29 designates a bearing block which is secured by means of screws 30, to any suitable part of the machine, and pivotally mounted in said bearing block 29, by means of a pin 31, is a lever 32, said lever being provided on its free end with an operating handle 33. Secured as at 34, to the traveling carriage 18, is a flexible cord 35, said cord passing around the rollers 27 and 28, and having its free end secured, as at 36, to the operating lever 32.

The operation of the device is as follows: The operating lever 32 is so positioned that it is capable of being moved by the knee of the operator as he sits at the machine,

in turn secured by means of and it will be apparent that as said operating lever 32 is moved about its pivot, the reading glass 16 is moved from left to right in Fig. 1, over the manuscript -10, which is positioned on the copy-holder board 7. As the reading glass is moved to the extreme right position, pressure on track in different planes,

. the lever 32 is released, at which time under the influence of the spring drum 14 and the flexible cord 24, the reading glass 16 is returned to its normal position at the lefthand side of Fig. 1, the operatinglever 32 returning to its normal position under the influence of the flexible cord 35. ,The reference character 41 designates a stop which is secured to the track 12 and limits the movement of the travelin a direction to the left in ig. 1.

I claim:

1. A reading glass holder comprising a pair of spaced brackets, a track having one of its ends downwardly bent and supported by'said brackets, a carriage substantially U-shaped in cross section adapted to receive said track between its extended members, rollers mounted in said carriage and adapted to engage opposite sides of the a reading carried by said carriage, a spring rum carriage 18 in lass mounted on the downwardly bent end of said track, means for connecting the spring spring drum, substantially as described.

reading glass holder comprising a plurality of supports arranged in spaced relation, a track carried by said supports andhaving one of its ends angularly disposed with relation to its main body portion, a carriage, rollers carried by the carriage and adapted to engage the opposite sides of said track to support the carriage thereon, a spring drum carried by the angularly disposed portion of said track and adapted to move the carriage in one direction, means for moving the carriage in the opposite direction, and means carried by the track to limit the movement of the carriage under the influence of the spring motor.
